Flooding Context

On Saturday, June 20, a nearly stationary line of thunderstorms dumped significant amounts of rain over the West Island in just a few hours. Several areas received rainfall totals of around 150 mm over a 24-hour period.

This rainfall, combined with precipitation that had already fallen earlier in the day, fell on saturated ground, leading to flash flooding. It is estimated that between 300 and 350 homes in Pierrefonds-Roxboro were affected by flooding or significant water accumulation. Some thunderstorms were accompanied by hail and caused power outages in the hardest-hit areas.

A coordinated response

From the first reports of flooding, teams from public works, the SPVM and the SIM were mobilized to assist residents affected by the flooding. The City also worked closely with Hydro-Québec to support efforts aimed at restoring electrical service as quickly as possible.

Follow-up on special collections of debris and contaminated Materials

Thanks to the sustained efforts of blue-collar crews and the extensive operations carried out by the borough over the past several weeks, the situation has nearly returned to normal in the affected neighbourhoods.

To help complete recovery efforts as quickly as possible, multiple crews and trucks were deployed simultaneously throughout the borough to collect debris and contaminated materials that had accumulated following the severe weather events. These sustained efforts made it possible to process an exceptional volume of materials in the hardest-hit areas.

The special collection will nevertheless continue until the end of July and will take place on July 18 and 25.

After this period, residents who still have materials to dispose of may use regular disposal services, including the Saint-Laurent ecocentre, or contact private companies that provide container rental services.

We thank residents for their cooperation and patience throughout this large-scale operation.

A Resilient and Supportive Community

At times like these, community solidarity is essential. We encourage residents who are able to do so to check in on their neighbours, especially seniors, people with limited mobility, and those living alone.

We understand the difficulties many residents are currently facing. Rest assured that the City remains fully committed to supporting those affected and restoring services as quickly as possible.
